TabActivity横向布局

来源：互联网发布：比价网源码编辑：程序博客网时间：2024/06/05 14:17

系统默认的TabWidget是horizontal的：

源码一部分

private void initTabWidget() {

setOrientation(LinearLayout.HORIZONTAL);

所以我们需要自己改变tabwidget的orientation

TabWidget widget = mHost.getTabWidget();
widget.setOrientation(LinearLayout.VERTICAL);

布局文件

<?xml version="1.0" encoding="utf-8"?><TabHost xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/host"android:layout_width="fill_parent"android:layout_height="fill_parent"    >    <LinearLayout         android:layout_width="fill_parent"        android:layout_height="fill_parent"        android:orientation="horizontal"        >        <TabWidget             android:id="@android:id/tabs"android:layout_width="180px"            android:layout_height="fill_parent"android:background="#ffffffff"android:padding="10dp"            />        <FrameLayout             android:id="@android:id/tabcontent"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:layout_weight="1"            />    </LinearLayout></TabHost>

Activity code

package com.kingkong.testtab;import android.app.ActivityGroup;import android.content.Intent;import android.os.Bundle;import android.widget.LinearLayout;import android.widget.TabHost;import android.widget.TabHost.TabSpec;import android.widget.TabWidget;import android.widget.TextView;public class TestTabActivityActivity extends ActivityGroup {TabHost mHost;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);                mHost = (TabHost) findViewById(R.id.host);        mHost.setup(getLocalActivityManager());        TabWidget widget = mHost.getTabWidget();        widget.setOrientation(LinearLayout.VERTICAL);                addTab("jjjjavvva", "java", JavaActivity.class);        addTab("aaandroid", "android", AndroidActivity.class);        addTab("hhhadoop", "hadoop", HadoopActivity.class);    }        private void addTab(String indicateText, String tag, Class<?> className) {    TextView tab = new TextView(this);        tab.setLayoutParams(new LinearLayout.LayoutParams(-1, 50));        tab.setBackgroundResource(R.drawable.tab_bg);        tab.setTextColor(0xff000000);        tab.setText(indicateText);        TabSpec specJava = mHost.newTabSpec(tag);        specJava.setIndicator(tab);        specJava.setContent(new Intent(this, className));        mHost.addTab(specJava);    }}
